Abstract - As construction in India and other developing
and performance as a structural material. Toovercome such situation researchers introducing some substitution of material which is cheaper in cost and easily available use of industrial waste in concrete.
countries increases, the consumption of energy and resources is also increasing in an alarming way. Most of the developing nations have reduced the usage of virgin materials in construction, due to consumption of energy and resources is increasing in an alarming way, so they focused on the environment and safeguarding of natural resources and recycling of wastes materials. Many industries produce lot of waste products which is disposed into landfills. This material can be used in construction industry as alternative to conventional materials. Such practice conserves natural resources and reduces the space required for the landfill disposal of these waste materials. Highperformance concrete appears to be a better choice for a strong and durable structure. In this project, investigations were carried out on strength properties such as compressive strength and flexural strength of M40 grade of HPC mixes with different replacement levels such as 05%, 10%, 15% and 20%, of marble powder with cement and 20%, 30%, 40%, 50%, and 60% of foundry sand with fine aggregate by adopting watercement ratio of 0.42 and combined of both with different replacement levels such as (5%+20,30,40,50,60%),(10%+20,30,40,50%),(15%+20,30%). Conplast SP430 is based on can be used as a super plasticiser for better workability for high performance concrete. The HPC mix, grade M40 concrete is designed as per IS 10260-2009 Guide for selecting proportions for high strength concrete materials. Mechanical characteristics like Compressive strength and Flexural strength were examined. The result of these investigations demonstrates the strength characteristics of marble powder, foundry sand based concrete mixes
1.1 Material & Properties Cement: OPC of grade 43 was used for casting all the specimens should be confirming to IS was used for the present experimental investigation. Fine aggregate: Clean and dry river sand available locally was used. Sand passing through IS 4.75 mm sieve was used for casting all the specimens. Specific gravity and fineness modulus is 2.55 and 3.45 respectively Coarse aggregate: Coarse aggregate passing through 20 mm sieve as given in IS 383 – 1970 was used for all the specimens. In addition to cement paste- aggregate ratio, aggregate type has a great influence on concrete dimensional stability. Specific gravity and fineness modulus is 2.906 and 3.49 respectively. Foundry sand: Foundry sand is high-quality uniform silica sand that is used to make moulds and cores for ferrous and nonferrous metal castings. Foundry sand is a by- product of the castings industry typically comprising uniformly sized sands with various additives and metals associated with the specific casting process. Foundry sand is the most essential raw material and its importance is sometimes forgotten amongst Foundry personnel. Foundry sand is as used by Foundries is desired for its thermal resistance and availability. Most metal casting sand (FS) is high quality silica sand with uniform physical characteristics. Specific gravity of foundry sand is 2.44and fineness modulus is 2.09

Marble Powder: Marble is a metamorphic rock resulting from the transformation of a pure limestone composed solely of calcite (100%CaCO3). Chemically, marbles are crystalline rocks composed predominantly of calcite, dolomite or serpentine minerals. The main impurities in raw limestone (for cement) which can affect the properties of finished cement are magnesia, phosphate, leads, zinc, alkalis and sulphides. A large quantity of powder is generated during the cutting process. Leaving these waste materials to the environment directly can cause environmental problems. Using marble powder in concretes and results about strength and workability were compared
1.INTRODUCTION A large number of researches have been directed towards the utilization of waste materials which are easy available and cheaper in cost. For the construction industry, the development and use of waste material is growing rapidly Construction industry need huge amount of construction material and continuous dependence on natural virgin material will lead scarcity of the construction material and increase in cost of material and construction. In recent times, many researches are going on for improving the properties of concrete with respect to strength, durability,
